International company's plan for multi-billion-dollar data centre in regional Qld

A proposed $31.9 billion data centre project is set to be constructed in regional Queensland, despite concerns over water and energy consumption. This announcement comes amid national debates on the environmental impact of data centres, particularly in light of the energy demands of artificial intelligence. The project, known as the Western Downs Digital Park, is proposed for a 725.5-hectare site near Dalby, approximately 250 kilometres northwest of Brisbane.

Developed by Singapore-based Zerra DC, the facility will consist of a 37km north-west location currently occupied by a 24,000-head feedlot owned by Wambo Cattle Company.

While the data centre is strategically located near major regional power stations, there are fears regarding energy consumption and water security as more data centres are developed and constructed across the country. The federal government is in the process of crafting new national rules for data centre energy use, which includes a requirement for them to purchase power from renewable sources.

In Southern Queensland, Toowoomba Regional Council has recently moved to ensure that data centres do not encroach on drinking water sources within the region. Councilor Rebecca Vonhoff emphasized the council's national leadership in this matter, citing their personal connection to water issues following devastating droughts.

The Western Downs Digital Park plans to prioritize air-cooled technology and avoid reliance on town water infrastructure, although construction and operation will still be water-intensive. During the construction phase, the site would require around 522 kilolitres of water per day, followed by 26.9 megalitres per building during a one-time flush-and-fill process - equivalent to the average annual water use of 155 Australian households.

Even under regular operation, the centre would use approximately 16.5 kilolitres of water per day. Water would be sourced from coal seam gas, rainwater harvesting, water delivery, recycled wastewater, and on-site surface water, according to the development application.

Regarding power, Western Downs Mayor Andrew Smith highlighted the region's unique position as the "energy capital of Queensland," boasting a well-developed energy infrastructure. He stated that if more energy infrastructure is required, the region is ready to accommodate it. Community consultation is anticipated as a part of the proposal process, with Mayor Smith acknowledging that water and power-related concerns are of utmost importance to the local community.

Queensland Minister for Water Ann Leahy echoed these sentiments, emphasizing that the community should have a say in this major project proposal, just like any other development.
